Phys.org / Promise the Earth: Why real climate action means restraint
A new book by a Cambridge engineer and an Oxford theologian argues that our faith in technology to solve the climate crisis is distracting us from the uncomfortable truth: that saving the planet is neither a task for future ...
Medical Xpress / More social support can sometimes lead to more—and sometimes to less—use of mental health care
People with severe mental health problems are generally thought to receive more care when they are unwell, and less care once they begin to recover. According to researcher Thijs Beckers, however, the reality is more nuanced. ...
Phys.org / The 'Little red dots' observed by Webb were direct-collapse black holes
The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved ...
Phys.org / Pulsar timing hints at a nearby dark matter 'sub-halo'
A group of US astronomers may have uncovered the first evidence for a dark matter sub-halo lurking just beyond our stellar neighborhood. Reporting their findings in Physical Review Letters, a team led by Sukanya Chakrabarti ...
Phys.org / Scientists discover 'levitating' time crystals that you can hold in your hand
Time crystals, a collection of particles that "tick"—or move back and forth in repeating cycles—were first theorized and then discovered about a decade ago. While scientists have yet to create commercial or industrial ...
Phys.org / Subaru observations suggest an intrinsic gap in NGC 5466's tidal stream
Astronomers from the National Astronomical Observatory of Japan (NAOJ) and elsewhere have used the Subaru Telescope to perform deep imaging observations of a distant globular cluster known as NGC 5466. The observational campaign ...
Phys.org / China's emissions policies are helping climate change but also creating a new problem
China's sweeping efforts to clean up its air have delivered one of the biggest public health success stories of recent decades. Since the Air Pollution Prevention and Control Action Plan was launched in 2013, coal-fired power ...
Phys.org / New record of great white shark in Spain sparks a 160-year review
On April 20, 2023, a juvenile great white shark (Carcharodon carcharias) measuring approximately 210 cm and weighing between 80 and 90 kg was incidentally caught by local fishermen off the coast of the eastern peninsula within ...
Phys.org / Social media feeds: Algorithm redesign could break echo chambers and reduce online polarization
Scroll through social media long enough and a pattern emerges. Pause on a post questioning climate change or taking a hard line on a political issue, and the platform is quick to respond—serving up more of the same viewpoints, ...
Phys.org / 7,000-year-old deer antler headdress from Eilsleben illustrates contact between hunter–gatherers and early farmers
Central Germany is among the regions where, as early as the mid-6th millennium BC, farmers displaced the Mesolithic hunter–gatherers from the fertile loess soils. Soon after this migration, however, exchange began between ...
Phys.org / 7,000 years of change: How humans reshaped Caribbean coral reef food chains
Human activity has lessened the resilience of modern coral reefs by restricting the food-fueled energy flow that moves through the food chains of these critical ecosystems, reports an international team of researchers in ...
Phys.org / Current flows without heat loss in newly engineered fractional quantum material
A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong Xu at the University of ...
